BY A BESTSELLING AUTHOR TEAM--THE MUST-HAVE REFERENCE ON WATER TREATMENT PRINCIPLES FOR STUDENTS From the same distinguished author team that brought you the bestselling reference Water Treatment comes this new offering for students wishing to gain a solid understanding of the latest developments in water treatment processes. It maintains the same quality writing, illustrations, and worked examples as the author team's larger Water Treatment but does so in a more digestible and specifically focused format. It covers conventional processes like coagulation, flocculation, sedimentation, and filtration--but unlike any other water treatment book of this size, it gives equal coverage to advanced technologies like adsorption, ion exchange, reverse osmosis, and advanced oxidation. Complete with example problems, chapter summaries, end-of-chapter review questions, and access to a solutions manual online, Principles of Water Treatment provides all of the tools necessary for a civil or environmental engineering or water resources student to launch a successful and rewarding career. MWH is a global consulting firm with more than 7,000 professionals and 180 offices in thirty-five countries that provides services to a full range of water-related projects and programs ranging from water supply, treatment and storage, dams, water management for the natural resources industry, and coastal restoration to renewable power and environmental services.
